ATTACHMENT FOR PLOWS.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed October 26,1905. Serial No. 284,512.

To all whom it may concern:

Be it known that I, ANTHONY THIELEN, a citizen of the United States of America, and a resident of Bryant, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Attachments for lPlOWs, of which the following is a specification.

My invention relates particularly to an attachment for plows which has for itsmain object the provision of means for lifting and straightening out cornstalks after they have been severed from their roots by a stalk-cutting machine, so as to place them in a position to readily enable the plow to turn them under, the lifter of the attachment simply floating or traveling ahead of the plow-point.

Another object of my invention is to provide simple means whereby the lifter can be readily secured to and removed from the plow-beam of an ordinary plow.

With these and other objects in view my invention consists in the novel features of construction, as hereinafter described and claimed. 1

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which Figure 1 is a perspective View showing my improved attachment secured to the plowbeam of an ordinary plow. Fig. 2 is a plan view, the spring being omitted. Fig. 3 is a vertical transverse section thereof, taken on the line 3 3 of Fig. 2 looking in the direction of the arrows. Fig. 4 is a vertical transverse section taken on the line 4 4 of Fig. 2 looking in the direction of the arrows. 1 Fig. 5 is a side elevation of the attachment, showing the normal position of the lifter in full lines and its raised position in dotted lines. Fig. 6 is a detail perspective view.

My attachment is shown in Fig. 1 of the drawings mounted upon the forward end of a plow-beam of a stubble-plow in position for use and secured by means of front and rear clamps located one in advance of the other. The front clamp comprises a plate 1, located at the inner side of the plow-beam, having inset ends 1, providing a recess for the front end of a spacing-plate 2, also located at the inner side of the plow-beam and extending lengthwise thereof, a plate 3, located at the outer side of the plow-beam, a lower bolt 4, and an upper bolt 5. The rear clamp comprises an inner plate 6, an intermediate plate 7, located against the rear end of the spacing-plate 2, having an upward extension 7 formed with a hole 7 b and spaced from the inner plate 6 by a lower collar 8 and an upper collar 9, an outer plate 10, a lower bolt 11, extending through the inner plate, the lower collar 8, the intermediate plate 7, and the outer plate 10, an intermediate bolt extending through the intermediate plate 7 and the outer plate 10, and an upper bolt 12, extending-through the inner plate 6, the upper collar 9, and the intermediate plate7.

13 is a pivot-stud extending through and secured to the front end of the spacing-plate 2 and projecting through the inner plate 1 of the front clamp. Upon this pivot-stud my improved stalk lifter and straightener is mounted and secured by means of a washer 14 and a nut 15. This stalk lifter and straightener is constructed in one piece with a rearwardly-extending arm 16, located between the inner plate 6 and the intermediate plate 7, and normally rests upon the lower collar 8, with a hook 16 extending downwardly-from the rear side of the rear clamp to a point under the latter and adjacent to the plow-point and with an upwardly-extending arm 16 at the front end of the lifter having a hole 16 at its upper end. While the lifter may rest upon the lower collar 8 by its own gravity if of suflicient weight, yet I prefer to employ a tension-spring 17, having a hook 17 a at its rear end connected with the hole 7 of the intermediate plate 7 of the rear clamp and a hook 17 at its front end connected with the hole 16 of the upwardly-projecting arm 16 of the lifter. This arrangement permits the lifter to readily yield when the hook 16 meets with a solid obstruction in its path.

For the purpose of quickly removing any accumulation of material whereby the hook 16 may become clogged I provide the means now described.

18 is an eye secured to the heel of the hook 16*, and 19 is an eye secured to the intermediate plate 7. To the eye 18 I secure the inner end of a flexible connection-such as a cord, rope, or .small chain 20and pass the latter through the eye 19 to a point adjacent to the plow-handles, where it rests upon a cross-brace in convenient position for the 0 erator to grasp the outer end for lifting t e hook 16*" when it becomes necessary to clear the hook.

As shown in the detail perspective view, Fig. 6, the inner plate 1 of the front clamp, the spacing-plate 2, and the intermediate plate 7, the eye 19 thereon, the lower collar 8, and the upper collar 9 of the rear clamp may all be cast in one piece.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. An attachment for plows comprising front and rear clamps, adapted to be secured one in advance of the other to the forward end of a plow-beam, and a lifter, pivoted to the front clamp, formed with a rearwardlyextending arm, passing through and normally supported by the rear clamp, and a hook extending downwardly from the rear side of the rear clamp to a point under the latter.

4. An attachment for plows comprising front and rear clamps, a spacing-plate within the clamps, a lifter, pivoted to the front clamp, formed with an upwardly-projecting arm, a rearwardly-extending arm, normally supported by the rear clam and a hook extending downwardly from t e rear side of the rear clamp to a point under the latter, and a spring, for holding the lifter in operative position, connected at one end to the rear clamp and at the other end to the upwardly-proj ectinglarm 5. attachment for plows comprising a front clamp, a rear clamp having a hole at its upper end, a lifter, pivoted to the front clamp, formed with an upwardly-projecting arm, having a hole at its upper end, a rearwardlyextending arm, normally supported by the rear clamp, and a hook extending downwardly from the rear side of the rear clamp to a point under the latter, and a tension-spring beam, a pivot-stud secured to-the front clamp, a rear clamp, adapted to be secured to the plow-beam behind the front clamp, a lifter, mounted upon the pivot-stud, formed with a rearwardlyextending arm, passing through and normally supported by the rear clamp, and a hook extending downwardly from the rear side of the rear clamp to a point under the latter.
